Wireless considerations

2.1 Power up sequence
The Rosemount 248 Wireless Transmitter and all other devices should be
installed only after the Wireless Gateway ("Gateway") has been installed and
is functioning properly. Wireless devices should also be powered up in order
of proximity from the Gateway, beginning with the closest. This will result in
a simpler and faster network installation. Enable Active Advertising on the
Gateway to ensure new devices join the network faster. For more
information see the Emerson Wireless Gateway
2.2 Antenna position
The internal antenna is designed for multiple mounting orientations. The
transmitter should be mounted according to best practices for your
temperature measurement application. The transmitter should be
approximately 3 ft. (1 m) from any large structure or building to allow clear
communication to other devices.
2.3 Field Communicator connections
The power module must be installed in the device for the Field
Communicator to interface with the transmitter. The Field Communicator
connections are located on the Green Power Module. To communicate to
the transmitter, begin by removing the power module cover. This will
expose the HART
Module. Next, connect the Field Communicator leads to the COMM port
connections on the Green Power Module.
This transmitter uses the Green Power Module; order model number
701PGNKF. The power module is keyed and can only be inserted in one
orientation. Field communication with this device requires a HART-based
Field Communicator. Refer to
Field Communicator to the transmitter.
